Statistics: figures and conclusions.

For collecting statistics, you could simply add an extra column with the game version (without changing the rating calculation), since the version is indicated in the report.

And to make the distinction, as boovli noted, you could just add a column to the table. If, of course, it isn't written to the database and the field is just decorative — then yes, that's unfortunate.

Let me try to clarify. The HeroesWorld report system and the rating calculation website are two completely unrelated resources. The site that calculates the rating simply scans the forum and reads reports written according to a template. The fact that we select a version when submitting a report — that is not displayed in the report itself. I am almost certain that this information does go somewhere into the database, but nothing more. In other words, to somehow implement a separation of ratings, the report system itself would need to be reworked so that the game version is displayed in the report (as a template, for example). But for that to happen, someone needs to do it, and the person who could do it hasn't visited this site for months, so even implementing such a simple feature is highly questionable.
